Title: Semiconductor device and manufacture of semiconductor substrate
Inventor: MUKAI MIKIO
IPC: H01L21/76
Filed: 1989-12-15
Abstract: PURPOSE:To reduce parasitic capacitance, and to improve characteristics by electrically connecting diffusion region s in a lowermost layer in a plurality of diffusion regions separately formed in a plurality of element forming regions isolated extending over a peripheral section from a lower section by a wiring layer while the wiring layer is led out of a section except the element forming regions. CONSTITUTION:Two element forming regions 2 are isolated extending over peripheral sections from lower sections by SiO2 films 1 mutually. Consequently, parasitic capacitance CCS among each collector region 11 and 16 of an NPN transistor Q1 and an NPN transistor Q1 formed in each element forming region 2 and 3 and a silicon wafer 41 can be removed substantially. As a result, working speed in a process transferring from a cut-off region to a saturation region on the characteristics of an NPN transistor Q2 is increased. A wiring layer 4 by a polycrystalline silicon layer is shaped to the lower sections of the element forming regions 2 and 3. Accordingly, only Al wirings may be formed to the upper sections of the element forming regions 2 and 3, thus improving the degree of freedom of an Al wiring pattern.

Title: Manufacture of diode
Inventor: IWAO HIDEMI
IPC: H01L21/329
Filed: 1990-11-29
Abstract: PURPOSE:To avoid the development of such defects as the formation of the protruding edge of an upper electrode or a semiconductor layer sagging down to come into contact with the other electrode or the semiconductor layer by a method wherein, before etching away a lower electrode, a resist layer is light-ashed. CONSTITUTION:A resistance layer 2, a lower electrode 3, a semiconductor layer 4 and an upper electrode 5 are successively formed on an insulating substrate 1. Next, when the upper electrode layer 5 is etched away using a resist layer 6 as a mask and then the sumiconductor layer 4 comprising an N type film, an I type film and a P type film is etched away also using the resist film 6 as a mask, a protruding edge part 5a is formed on the periphery of the upper electrode 5. Next, the resist layer 6 is etched away by light-ashing step further etching away the lower electrode layer 3 using the ashed resist layer 6 as a mask. Thus, the protruding edge part 5a of the upper electrode 5 can be easily removed by the light-ashing step of the resist layer 6 without excessively etching away the lower electrode 3. Through these procedures, the probable development of such defects as the sagging of the upper electrode edge coming into contact with the sides of the lower electrode 3 or the semiconductor layer 4 can be avoided.

Title: Method and device for temperature correction of electronic measuring instrument
Inventor: KUNUGI SATOSHI
IPC: G01D3/028
Filed: 1988-12-23
Abstract: PURPOSE:To take a measurement without any error without being affected by temperature at the time of the measuring operation by storing a storage device previously with the quantity of deviation of a measured value from a real value due to temperature variation as to each temperature value, and correcting the measured value by using the quantity. CONSTITUTION:The potential difference between two points C and D of a converting device 2 composed of one strain gauge 2a is adjusted to zero when no body to be measured is mounted on a load meter 1. When a body to be measured is mounted on, the strain gauge 2 is strained in proportion to its weight and the potential difference which is proportional to the quantity of the strain is generated between the points C and D. This potential difference is led to a CPU 12 through an amplifier 9 and an A/D converter 10 as a digital value which is proportional to the weight of the body to be measured. The temperature at the time of the measuring operation, on the other hand, is inputted to the CPU 12 from a temperature measuring instrument 4 through an A/D converter 10 and the quantity of the deviation of the measured value corresponding to the temperature is read by the CPU 12 out of the storage device 3 to correct the measured value with the read value, thereby displaying the result on a liquid crystal display board 18.

IPC: H01L21/768
Filed: 1993-12-24
Abstract: PURPOSE:To enhance the reliability of a semiconductor device by preventing a product principally comprising aluminium fluoride from depositing in a through hole of a multilayer wiring. CONSTITUTION:A lower layer wiring pattern 106 comprising a laminate of a tungsten film 104 and an Al-Si-Cu alloy film 105 is formed on a semiconductor substrate 100. After depositing silicon dioxide 107 as an interlayer isolation film, photoresist is applied and a resist pattern 108 is formed by a well-known lithography.

Title: Image pickup device
Inventor: OKUBO MASATOSHI
IPC: H04N5/376
Filed: 1989-12-19
Abstract: PURPOSE:To attain sharp pickup even from an object with deficient illuminance by detecting lightness of an object with an optical sensor and adjusting the exposure time of a solid-state image pickup element based on the detection output so as to increase the sensitivity for long time exposure sufficiently when a dark object is picked up. CONSTITUTION:A detection output signal from an optical sensor 15 sensing the lightness of an object is fed to an exposure time control circuit 7. How much the exposure time of a CCD 3 is to be set is decided based on the inputted detection signal by the control circuit 7. Thus, what field the exposure time T for the long time exposure in the case of picking up a dark object is to be set is decided automatically. An exposure time control signal CL1 from the exposure time control circuit 7 is fed to a CCD drive circuit 4. Since the period of a field shift pulse FS outputted to the CCD 3 is changed in response to the darkness of the pickup location, the pickup with high sensitivity is always implemented.
